Well, to tide me over until I'm ready to go into the $1k range I got myself an MHDT Paradisea NOS DAC with a Tung Sol 2C51 tube, and my goodness I am really enjoying it! I now find myself loving the music again and not getting bogged down by the details! Granted my previous DAC (MSB Link III, and briefly the DAC in my Classe SSP-300 pre/proc) was a weak link in my system, but the kind of smooth, coherent, emotive sound that the Paradisea puts out really suits me. Now I remember why I cling to my tube pre-amp. The soundstage can be a little skewed IMO, and it's not the most detailed, but it doesn't really bother me.
I'd really be interested to read a comparison between the Havana and the TDac. I know there's a thread out there, but only one person had experience with both Havana and TDac (not TaDac).
I'm guess I'm just going to have to get all 3 (DAC3, Havana, TDac) and decide which one to keep.
